This graph below shows the standard LED light spectrum (white curve) and the new BioUp (black curve). The peak of the blue-green light wavelength is clearly visible.
The importance of light for performance
Today, people spend an average of more than 90% of their time indoors, of which 36% is spent in the workplace. The more time you spend indoors, the less you take advantage of the benefits of light. Consequently, people do not get to enjoy enough daylight, which helps: See better, Feel better, To perform better
Light has a visual effect (you see better), an emotional effect (you feel better) and a biological effect (you perform better).
Although light has a biological effect on overall well-being, the lux levels of indoor lighting are usually decided according to the visual function of the light (500 lux), which are usually lower than the recommended light levels for biological effects.
What is melanopic light?
Melanopic light is a part of biological light that plays an important role in synchronizing the body's circadian rhythm with the non-visual effects of light. When
melanopic lighting is used in an office building, the benefits of daylight are brought indoors, which improves visual comfort, well-being and performance. Melanopic light has a direct connection:
Light intensity, Circadian rhythm, Spectrum of light
A good office space is designed with employees' well-being in mind:
Here are pictures of the solution implemented at EPTA GROUP:
Customer comments:
When we installed MasterConnect together with the BioUp system in an office where there was hardly any daylight (those small windows!), the immediate feedback was: "Why don't we have more of this?!"
I wanted to know what the customer really thought about the system when there are so many different options on the market. His answer was clear: "It's simpler than anything else."
Now this office is not only brighter; employees sleep better and wake up more refreshed. This is the magic of BioUp: adjusting lighting to natural circadian rhythms to improve well-being and energy levels.
The lamp is an AD-Lux aluminum frame linear lamp, in addition to BioUp, the lamp has an intelligent MasterConnect sensor system.

AD-Lux luminaires are manufactured and assembled in our own factory in Kaarina.
For us, quality, domesticity and responsibility are not just words - they guide everything we do.
The aluminum frames of the luminaires are manufactured using Mäkelä Alun's Swan-labeled recycled aluminum.
In our office luminaires, we use recycled polypropylene, which reduces plastic waste and our carbon footprint.
Each luminaire undergoes a strict testing process before delivery.
We verify connections, measure insulation resistance and test operation – every luminaire that leaves us has been switched on and tested in practice.
Quality is also supported by the LEAN operating model and certified ISO 9001 and ISO 14001 quality systems.
We are proud of Finnish work: our own manufactured luminaires have been awarded the Key Flag of the Finnish Work Association.
This means that more than half of the luminaire's costs come from domestic work and materials.
The components come from Philips/Signify in Poland, but all frame materials and assembly are made in Finland.
The linear luminaires of our own production have an aluminum frame and are equipped with Philips/Signify electronics – a life expectancy of up to 100,000 hours.
The light can be precisely controlled using lenses, and different power classes offer light between 4,000 and 40,000 lumens.
Our standard models are IP54 rated, and can be sealed to IP65 if required.
We customize luminaires according to your needs:
Our range includes three power classes: 15,000 / 30,000 / 60,000 lm, all IP65-rated.
Lens options enable precise direction of light – also horizontally, which allows glare to be minimized, for example on the road or in the neighborhood.
Our goal is to develop a biocomposite lamp that takes the recycling rate even further.
The AD Green series, which uses recycled polypropylene, is already in production.
An ecological, lightweight and modern solution – without compromising on light quality.
In addition to AD-Lux's own production, we also offer Signify LED panels and other high-quality lighting solutions for various applications.

Lumen
The word "lumen" comes from Latin and means "light" or "luminosity". It comes from the same root as the English words "illuminate" and "luminous".
In physics and measurement, the term "lumen" was introduced to describe the visible luminous flux, i.e. how much light a source produces in the spectrum visible to the human eye. It is an SI unit based on the candela, which measures the intensity of light in a given direction.
In other words: lumen measures how much light a source emits in total, while candela measures how intense the light is at a given angle.
Luminaire manufacturers state the lumen output of their luminaires. This information is crucial when planning the lighting of a project, for example using the DiaLux program.
Often, the power rating of a luminaire is also multiplied by the lumen/watt number. The more current is applied to the LEDs, the lm/W ratio starts to decrease after a certain point. The best efficiency is at nominal current. At AD-Lux, we prefer not to extract maximum power from the luminaire, so that the temperature management of the luminaire remains better under control and the lifespan of the luminaire remains at the expected level.
WATTAGE
The watt (W) is a unit of power that measures the transfer or consumption of energy over time. It is named after the Scottish engineer James Watt, known for developing the steam engine.
1 watt = 1 joule per second (J/s)
That is, if a device consumes or produces 1 joule of energy per second, its power is 1 W.
Difference between watts and lumens:
That's why LED bulbs are energy efficient: they produce more lumens per watt, meaning they use less electricity to produce the same amount of light.
Watts alone do not indicate energy consumption – time is also needed. Energy (Wh)=Power (W)×Time (h)\text{Energy (Wh)} = \text{Power (W)} \times \text{Time (h)}Energy (Wh)=Power (W)×Time (h)
📌 Example:
💡 Summary:
The temperature of a heat-radiating source, used to describe the color of its light.
Unit: kelvin [K]. The lower this value, the redder the light and the higher the value, the bluer the light. The color temperature of gas discharge lamps and semiconductors, unlike that of heat-radiating sources, is called "correlated color temperature".
Assignment of light colors to color temperature ranges according to EN 12464-1:
Light color - color temperature [K]
warm white (w) < 3300 K
neutral white (nv) ≥ 3300 – 5300 K
daylight white (dv) > 5300 K
The color temperature can also be adjusted, changing the color of the light from yellow to daylight and vice versa.
The color rendering index of a lamp or bulb, as specified in DIN 6169: 1976 or CIE 13.3: 1995.
The general color rendering index Ra (or CRI) is a dimensionless quantity that describes the quality of a white light source in relation to the reproduction of eight different test colors (see DIN 6169 or CIE 1974) in a reference light source.
The color rendering index measures the color rendering ability of eight different colors (R1-R8) and mathematically calculates the color rendering index Ra, which is the CRI reading. These eight different colors each correspond to a specific wavelength of the color. Therefore, only these eight colors are used to determine the CRI reading.
Eight different colors are measured when defining the color rendering index CRI. From these, the Ra number is mathematically calculated, which corresponds with a certain weighting to the numbers R1, R2, R3, R4, R5, R6 R7 and R8.
As can be seen from the image above, the color rendering index is missing several colors that are common in our everyday lives. For example, bright red. For this reason, additional measurable colors (R9-R15) have been developed, but these points are not used when calculating the color rendering index Ra. Ra is still calculated with only eight colors.
Seven additional colors for which better measuring devices also measure color rendering ability. However, these colors are not used to calculate the color rendering index (Ra). Note that skin color and leaf green are also included.
Since only eight colors are used to calculate the color rendering index (CRI), it is possible in practice that two different light sources with the same color rendering index do not have the same ability to reproduce colors. One light source may be significantly better than the other. However, the CRI number does not tell you this. The biggest difference is in the color red, i.e. reference color number 9 (R9). Skin color is also often reproduced differently.
R9, what about it. Is it important?
The color R9 represents bright red. Some swear by its importance, others think it is not important, especially since it is not even taken into account when determining the color rendering index. So is it fundamentalism to say that R9 is an important measurement parameter? Or is it just interesting? Or completely useless?
At the time when the color rendering index CRI was defined, there were no LED lights. The most common light was the incandescent lamp. Its light spectrum is very different from that of LED light. The spectrum of incandescent light starts from cold tones (blue) and increases linearly towards warm tones. The light therefore also produces a lot of red light (wavelength approximately 625-740 nm) so in practice the proportion of bright red light has not even had to be taken into account.

The MacAdam value is related to chromatic aberrations and illumination accuracy. It is based on the MacAdam ellipse, which describes how sensitive the human eye is to detecting color differences between light sources.
Key points about the MacAdam value:
✅ Expressed in SDCM units (Standard Deviation of Color Matching).
✅ The lower value, the more even and high-quality lighting.
✅ The higher value, the more color deviations are visible.
| MacAdam (SDCM) | Color deviation | Quality level |
|---|---|---|
| 1–2 SDCM | The merest | High-precision, laboratory |
| 3 SDCM | The merest | Quality lighting (LED, studio) |
| 5 SDCM | Visible difference | Standard LED lamp |
| 7 SDCM | Clearly noticeable | Inconsistent color |
| >7 SDCM | Large deviation | Poor quality |
MacAdam 3 SDCM is generally the recommended value for high-quality LED lamps and display lighting, for example.
UGR (engl. Unified Glare Rating) is a meter used in lighting that evaluates the amount of glare in a space. It helps determine how disturbing or unpleasant people find the lighting. The UGR value is especially important in offices, schools and other workplaces where glare can reduce work efficiency and comfort.
Meaning and calculation of UGR value
The UGR value is based on a complex calculation formula that takes into account several factors:
Based on these factors, it is calculated how much the glare from light sources irritates the people in the room. The higher the UGR value, the greater the glare experience.
UGR < 10: There is very little or no glare. This is suitable, for example, for spaces where very soft and even lighting is needed.
UGR 10–16: Glare is low and is usually not perceived as disturbing. This is a good lighting requirement for meeting rooms or office spaces, for example.
UGR 16–19: Glare is moderate. This value is suitable for most work environments, such as open-plan offices.
UGR 19–22: Glare can be a bit disturbing, but usually still tolerable in, for example, industrial and warehouse spaces.
UGR 22–25: Glare is already noticeable and can interfere with working.
UGR > 25: Glare is very distracting and uncomfortable, and can significantly impair concentration and work.
The UGR value (Unified Glare Rating) is not measured directly from the lamp, but is calculated from certain characteristics of the lamp and the space using a mathematical formula. Calculating the UGR value requires certain information about the space, the placement of the lamps and the characteristics of the light. It is therefore a calculated quantity based on several different factors, and it cannot be directly measured with, for example, a light meter.
Here is the calculation formula:
The UGR value is calculated based on the following factors:
Since the UGR value is based on a complex formula and several different parameters, specialized lighting design programs such as DIALux, Relux or other CAD-based lighting calculation programs are often used to calculate it. These programs are entered into:
Based on this information, the program calculates the UGR value in different places of the room and gives an estimate of how disturbing the glare is from different perspectives.

Lighting has a significant impact on a company's operations, energy costs and the comfort of the work environment. Many companies postpone lighting renovation due to high investment costs, but financing solutions offer the opportunity to carry out modernization without a large one-time cost. Here are reasons why it is worth financing lighting renovation.
New, energy-efficient LED lighting reduces energy consumption by up to 50–80% compared to old fluorescent or halogen lamps. With a financed solution, a company can immediately benefit from the savings without a large capital investment. Monthly savings on the electricity bill can even cover the financing costs, making the investment pay for itself. By connecting the luminaires to a smart lighting solution, even more savings can be achieved, as the lights are only on where people move.
High-quality lighting improves employee comfort and efficiency. The right lighting reduces eye strain, improves accuracy and reduces errors, which is especially important in industries, warehouses and offices. By investing in financing, a company can quickly upgrade its lighting without financial risk.
Financing models such as leasing or installments allow for investment without tying up capital. This leaves the company with more funds for other business development projects and secures cash flow. Lighting renovation can be implemented without significantly straining the company's budget.
LED lighting reduces a company's carbon footprint and supports sustainable development goals. In many industries, environmental responsibility is a competitive advantage, and modern lighting can help a company improve its image and meet increasingly stringent energy efficiency requirements.
LED lights last significantly longer than traditional light sources, reducing maintenance needs and costs.
A funded lighting upgrade is a smart way to improve a company's energy efficiency, work environment and cost structure without a large initial investment. It enables immediate savings, preserves cash flow and promotes environmental responsibility. By investing in modern lighting, a company creates a competitive advantage and ensures a sustainable future
Reference on investment payback period and financing:
In this example, AD Linear luminaires were installed in the premises, which also have Philips Masterconnect control. With the entire project financed, this means that the investment in the lighting project is practically free.
